Manchester United manager Ole Gunnar Solskjaer has said he will continue to pick Ander Herrera for the rest of the season despite the Spaniard nearing an Old Trafford exit.

Sources have told ESPN FC that the midfielder is expected to leave on a free transfer in the summer and is close to committing to Paris Saint-Germain.

Herrera is sidelined with a thigh injury -- that Solskjaer speculated could have been caused by the uncertainty surrounding his future -- but the Norwegian suggested the 29-year-old could still play a key role before May.

"Maybe the future might have been worrying him and that's part of the reason he's injured," Solskjaer told a news conference on Friday. "Who knows? He doesn't know.

"Hopefully he can be available for Chelsea or Manchester City but I'm not sure. He got another muscle injury.

"He loves to play and he's not very happy when he can't help his teammates. He is always giving his all, it doesn't matter if it's five weeks or five years on his contract."
